Description
Technical field
The utility model relates to the injection mold of the large frame of a kind of handset front case, relates in particular to the super narrow kirsite inserts precise injection mould of the large frame of a kind of handset front case.
Background technology
At present, the large frame of handset front case is generally kirsite insert-molding, and plastic material is PC+30GF, and inserts material is kirsite; Product entirety is frame-type, and length direction has super narrow frame; Appearance requirement Vacuum Deposition.
In prior art, in die industry, common preparation method is:
First-selection, kirsite inserts die cast.As shown in Figure 1, for preventing finished product distortion, conventionally first the centre of kirsite inserts 01 is added and does some passive false muscle 02, the monolateral first reserved 0.15mm～0.2mm of a middle circle inside casing size;
Then, by injection molding, the semi-finished product of kirsite inserts 01 are put into injection mould insert-molding, make the semi-finished product that comprise frame 03 as shown in Figure 2;
Afterwards, then by secondary finish-milling processing on CNC lathe, the false muscle 02 of centre is removed, be processed into finished product.
At least there is following shortcoming in above-mentioned prior art:
In the middle of in the time doing kirsite inserts, must add and do some passive false muscle connections, for providing intensity, following process side button bit for the first time ensures, and the distortion of avoiding injection mo(u)lding after-contraction to cause, for avoiding the follow-up secondary operations of CNC to remove the false injury of tendon and muscle and inside casing, a middle circle inside casing size is monolateral must first be reserved 0.15mm～0.2mm and treat that follow-up secondary operations removes in the lump; There are some potential problems in product: clamping location must be precisely in the follow-up secondary operations of CNC, after add and easily injure product man-hour, after add products formed and yielding in man-hour, thereby cause fraction defective to increase, cause the increase of production cost.
Utility model content
The super narrow kirsite inserts precise injection mould of the large frame of handset front case that the purpose of this utility model is to provide a kind of structure and technique is simple, yield rate is high, cost is low.
The purpose of this utility model is achieved through the following technical solutions:
The super narrow kirsite inserts precise injection mould of the large frame of handset front case of the present utility model, comprise front cavity, rear cavity, described rear cavity is provided with rear mold module, the middle part of described rear mold module is laterally provided with 1 to 3 runner, and the edge of described rear mold module is provided with multiple guide protrusions with gradient.
The technical scheme being provided by above-mentioned the utility model can be found out, the super narrow kirsite inserts precise injection mould of the large frame of handset front case that the utility model embodiment provides, because the middle part of rear mold module is laterally provided with 1 to 3 runner, the edge of rear mold module is provided with multiple guide protrusions with gradient, therefore the muscle that can not rehearse in the centre of kirsite inserts connects, a middle circle inside casing size is not done reserved, the side button bit rheo-die-casting moulding of product frame, prevent deformation of products in moulding, structure and technique are simple, yield rate is high, cost is low.

Detailed description of the invention
To be described in further detail the utility model embodiment below.
The super narrow kirsite inserts precise injection mould of the large frame of handset front case of the present utility model, its preferably detailed description of the invention be:
Comprise front cavity, rear cavity, described rear cavity is provided with rear mold module, it is characterized in that, the middle part of described rear mold module is laterally provided with 1 to 3 runner, preferably 2 runners, and the middle part of described runner is provided with runner sucker.
The passage of plastic flow when described runner is the filling plastic product processing on mould, plays the effect of dowel after described runner moulding, can ensure the flatness of product.After filling plastic is complete, this part can connect together with shape and the product of a runner, forms a circular platform at the runner sucker place at runner middle part simultaneously, and runner sucker is in order to facilitate manipulator sucker on injection machine to hold the platform of shaped article.
The edge of described rear mold module is provided with multiple guide protrusions with gradient, play the guiding role.
The surrounding on described rear cavity top is respectively equipped with rear mode slider.The rear mode slider of surrounding can slide to surrounding respectively.
The super narrow kirsite inserts precise injection mould of the large frame of handset front case of the present utility model, by the design of kirsite inserts precise forming mold, completes one-shot forming and goes out final products, avoids secondary operations, reaches batch production; Reduce or avoid manufacturing procedure problem on deformation after the rear processing of products formed and product; Prevent Product Variant problem in plastic mould injection moulding.
Specific embodiment:
As shown in Figure 3, Figure 4, be to reduce processing problems after products formed, the centre of kirsite inserts 01 muscle that do not rehearse connects, and a middle circle inside casing size is not done reserved, the side button bit rheo-die-casting moulding of product frame 03.
